analogous articles from plastic substances, have lately been patented by Mr. C. H. Murray, of Loman-street, Southwark. The improvements consist principally in the novel construction of the die and the cutting table. The object in view is to so construct the die through which the clay is delivered and to lubricate the faces that it will be

FIC.4 a smoother and more even surface than hitherto, and will carry away with it a very thin film of lubri cating material, and will, therefore, be delivered with a perfectly smooth and even surface. We have shown in our engraving a side elevation of the complete machine, as well as the details of the lubricating machinery. The cutting table is exceedingly simple and efficacious ; the stream of clay passes from the die over rollers, and when a sufficient length to make ten or twelve bricks has run out, it is cut off by a wire placed near the mouth of the die, and the piece so cut off is passed forward by hand on to the cutting frame. A lever with a segment working a rack is then brought over, which actuates a thrust board, and the clay is pushed through the cutting wires and divided into from ten to twelve bricks, according to the gauge. bricks so cut are left on a movable hand board, upon which they are removed to the barrow without handling. The improvement in the face of the brick thus obtained is very conspicuous, for, as the clay is pushed through the wires, instead of the wires being pulled through the clay, the edges are not torn in finishing the cut. As the stream of clay is never shut off, as many bricks can be made with one cutting frame as with two when the stream issues alternately from two orifices, By the arrangement of placing a separate cutting wire at the mouth of the die, the difficulty of cutting true bricks from a continuous stream is overcome.
